## Summary

Hackaday editors Mike Szczys and Elliot Williams review a week of hardware hacks, including a 3D-printed research robot that offloads motor control to a remote Linux computer via ESP-NOW, and a security analysis of the 'Bracktooth' Bluetooth vulnerabilities affecting chips like the ESP32. They also discuss automating fishing boats with GPS-controlled trolling motors, building a miniature Hoover Dam in a backyard, and the history of the Gopher internet protocol. The episode highlights the contrast between complex industrial engineering and accessible maker projects.
